Improvement in bottle-stoppers



UNITED S'rafrns RICHARD BOLLERMAN AND DMINIK L. ROLLER-MANN, OF NEV YORK, N. Y.

IMPROVEMENT IN BOTTLE-STOPPERS..

Specification forming fart of Letters Patent No. 162,346, dated April 20, 1875; application filed April 2, 1875.

1' o all whom it may concern:

Be it known that we, RICHARD BOLLER- MAN and DOMINIK L. BoLLERnANN, both of the city of New York, in the county and State of New York, have invented a certain new and 'useful Improvement in Bottle-Stoppers, of which the following' is a specification:

This invention is illustrated in the accompanying drawing, in which- Figure 1 shows a vertical section; Fig. 2, a side elevation, and Fig. 3 a plan or top view.

Similar letters indicate corresponding parts.

Our invention relates in particular to stoppers for bottles used for putting up effervescent liquids; and consists mainly in a hapvalve, 7 combined with a plate which is adapted to be fastened on the mouth of a bottle, and is provided with an inlet-hole, whereby the bottle is adapted to be lled without removing the stopper, while the valve is held shut by the pressure ofthe contents. It consists, also, in a bottle-shell adapted to be interposed between the valve-plate and the mouth of the bottle, and which forms the connection of the said plate with the bottle, while its interior forms a chamber for the valve to play in. It consists, further, in a peculiar fastening for the valve-plates, consisting of a thumb-button,

which is pivoted on the side of the shell that connects the plate to the bottle, and is provided with one or more inclined lips adapted to catch overthe edge of the plate, as hereinafter fully set forth.

In the drawing, the letter A designates the neck of a bottle, which is provided with the ordinary neck-wire c, and on the mouth of which is fitted a cylindrical shell, B. rlhis shell B is held in place by means of branch wires b, connected to the neck-wire a, or by any other suitable means, and between it and the bottle may be interposed a packing-ring, in order to insure a tight joint. The bottleshell B is made with a dat upper surface, in order to form a seat for the Hap-valve C, which is composed of a piece of rubber, leather, or other suitable material, so shaped that it has a iap, C', as indicated in dotted outline in Fig. 3. The said flap-valve C is accurately fitted on the top of the shell, and is held thereon by means of a cap-plate, D, which is connected to the shell, on opposite sides thereof,

by means of a hinge-joint, o, on one side, and by means of a suitable fastening device on the other side. The valve C is preferably cemented or otherwise secured to the plate D, so that it partakes of a movement thereof, or, in other words, rises from its seat when the plate is raised, in order to admit of discharging the contents of the bottle; but, ifdesired, the valve may be put loosely in place. In the valveplate D is formed an inlet-hole, E, of such diameter relatively to the iap of the valve as to leave a shoulder aside of the hole to arrest an outward movement of the valve. The valve is capable of an inward movement, and plays in a chamber, F, formed by the interior of the shell B. rlhe valve-plate D is provided with a nipple, G, whichv forms a continuation ofthe hole E, and is adapt-ed to be adjusted under the spout of a bottle-filling apparatus.

When the nipple is thus adjusted, and effervescent or other liquid discharges from the filling apparatus, the discharging liquid displaces the valve C, and passes into the bottle. When the bottle becomes filled the valve G automatically closes, and is held in a closed condition by the outward pressure of the liquid, by which means escape of the liquid is prevented, and the bottle is thereupon rendered t for transportation.

It will be seen that by this mode of filling the bottle the stopperthat is to say, the valve ai' 'ts retaining-plate-may be fastened previous to filling the bottle, and the difficulty attending a fastening thereof after the bottle has been lilled is obviated.

The valve-plate D is fastened by means of a button, H, which turns on a pivot, d, projecting from a stud, I, formed on the side of the bottle-shell. The button H, in this example, has an oblong shape, and it is provided with thumb-ears, by means of which it can be conveniently turned. On one or opposite edges of the button are lips e, which are so formed with respect to the valve-plate D that by turning the button one or the other ot the lips is caused to catch over and jam the edge ofthe plate or a lug, f, formed thereon, and by this means the plate is firmly held in place. r)Che lips e are inclined for part or the whole of their length, as seen in Fig. 2, so that they readily catch over the edge ofthe valve-plate,

and no great exertion is required to ei'ect this object.

If desired7 only one of the lips e need be formed on the button H; but We prefer to use two, so that in case one becomes worn or broken the other may be used in its stead.

What we claim as new, and desire to secure by Letters Patent, is-

l. In a bottle-stopper, the combination of the Hap-Valve G and hinged plate I), Which is adapted to be fastened on the mouth of a bottie, and is provided with an inlet-hole7 E, substantially as described.

2. In combination with the plateD and llapvalve C, the shell F, adapted to be fastened on the mouth of a bottle, substantially as described.

3. The thumb-button H, provided with one or more inclined lips, f, in combination With the shell E and plate I), substantially as dcscribed.

In testimonyT that We claim the foregoing We have hereunto set our hands and seals this 25th day of March, 1875.
